Re: archivalness of gum
 
 
Hey Judy,
 
Well, my big bonanza print sale was from a corporate art dealer who  
was buying artwork for a big new company down here.  She really liked  
the alt process work, which was the majority of what I had to show  
her-- actually, I think the brush marks really appealed to her -- and  
she initially told me on the phone that she was interested in only a  
few pieces.  When she got here, though, she ended up commissioning  
nearly 50 pieces.  What can I say?  I bombarded her with boxes and  
boxes of prints. :)  I think the reason she wanted me to do them as  
digital prints, is simply because she purchased so many.  Printing  
them all in some alt process (at the size she wanted, which was  
fairly large), would have been very expensive, time-consuming, and  
slow-going.  I think she knew the digital prints would be faster  
(there was a deadline), and certainly less expensive, and she was  
correct on both those counts.  Also, about half were color.  (She did  
ask me, though, if I could recreate those brush marks via the  
computer.  Ahem.  I just pretended like I didn't hear that part.)
 
I agree about gum.  I never thought for a minute that gum isn't  
archival.  I was very surprised when the person asked me that  
question about putting a layer of gum over platinum  (this person,  
who, admittedly, doesn't do alt processes and only prints  
digitally).  My reply was simply that maybe he should ask a painter  
who specializes in watercolors if he/she thinks their paintings are  
archival. ??  Still, I had always understood that platinum is the  
most archival photographic process --whatever that means.   I'm also  
guessing that a print is only as archival as the care that was put  
into the making of the print, at each step.  I mean, platinum may be  
archival, but if some crucial step was missing (the print wasn't  
cleared, or cleared improperly?),  then archival is relative, I  
guess.  Same with all the other processes.  As you say, other factors  
may impact that, too, including paper and proper storage.
 
I did print all that work on Hahnemuhle, but haven't tried any of  
their papers for alt printing yet.  I want to, though.  The  
Hahnemuhle I used, specifically for digital printing, was just their  
Photo Rag Paper, 308 gsm (which is available several places,  
including B&H).  I used the 17x22 size and was really pleased with  
the results.  The paper has enough of a texture that the image  
doesn't simply lay (lie?) there, looking flat on the paper, like I  
see with so many digital prints; while the resulting print is still  
smooth, the paper has a slight texture that gives some additional  
depth, or lift, or something, to the image/print. It's also fairly  
heavy, which I liked.  It really printed beautifully.  I especially  
liked what it did with b&w prints.

I absolutely REFUSE to comment in response to some asshole  
"curator" who decides gum can't do fine detai.... oh that's a

And Diana... you had a print buyer who insisted on inkjet pigment  
prints... which I found fascinating.  Did you get any idea why?  
(Whichever, congratulations on the sale !)  Do you suppose even  
from the most archival printer they're more archival than gum? 
 
And just what is it about gum that's supposed to be non archival --  
as if it matters.  I myself think that folks who assume there's  
going to be a civilisation on this old globe in 200 years that's  
capable of caring whether a print in some flooded, bombed, or  
otherwise relic "museum" has faded from its presumed pristine  
state... hasn't got enough in their head to stuff a strudel. 
 
Of course archivality is also a factor of the storage, the frame,  
the paper, and so forth... but good grief, that's the kind of  
preciosity gives me a pain in the brain... This from the culture  
that lionizes graffiti done with spray paints on crumbling  
masonry... cherishes singed posters and fragmented documents,  but  
frets that a gum print may not be perfectly archival... (to NO  
evidence, in fact against all evidence, if it matters). 
 
Why?  That's a no brainer -- because they know diddle about  
photography and double diddle about its history and triple diddle  
about why it could even be art. That is, they have no idea about  
photography being actual art. But they can understand in their  
little pea brains about "archival" --- they've probably never SEEN  
a gum print older than 30 years... but they feel free to sound off... 
 
I suppose I should apologize for being, um, so outspoken -- but  
that "curator" should apologize: This argument about archivality is  
an insult to photography.  Some of the most important prints and  
drawings not to mention paintings in the Western canon (not to  
mention tribal art) are melting, yellowing, crumbling, etc. before  
our eyes... And when the Italians, Greeks and Egyptians demand the  
Getty give their broken & cracked sculptures back, they don't worry  
about archival.. 
 
Why?  Because they KNOW that's art.  (Sublime, in fact.)  But they  
don't know that photography... even a platinum print (though the  
total platinum would sell for more on e-bay then their own chemical  
constituents) is judged by its archivality.  Tell them to, um, and  
go look at some old prints, like the yellowed and fading Rembrandts  
of holy awe. 
 
PS. Diana -- you mentioned that you printed your "collection" on  
Hahnemuhl -- which one?  I've done a lot of gums on Hahnemuhl &  
find it one of the best, but would love to try one that will also  
print in a printer, in case I haven't. 
 
And also, by the way, gum over platinum is an historic process --  
if memory serves (which I can't promise, MEMORY is NOT archival)  
Paul Anderson (heh heh) did it, but also I think Heinrich Kuhn,  
among others. I believe it was fairly well known...  Then again  
there were many kinds of "platinum" including a commercial  
"platinum paper" -- who was the Englishman who swore he'd stop  
photographing when that paper was discontinued?  He had the same  
name as a photo historian or other pioneer, but ... as noted, this  
memory is not archival. 
 
meanwhile, best to all...

Hey Chris-- Isn't platinum the most archival process?  At least,  
that's what I always tell people.  I'm sure I read that  
somewhere.  I did have someone ask me an interesting question  
recently that I never thought to ask anybody-- but I had made a  
gum over platinum print, and this person suggested that by using  
gum over the platinum, I was harming the platinum in some way--  
or, at least, somehow removing the archival nature of the  
platinum, since-- this person said-- gum isn't archival.  I think  
this person was only *assuming* that gum isn't archival-- really  
didn't know for sure-- but I thought it was an interesting question.

Good morning all! 
This may be a question for Gawain Weaver as I don't know who else  
on the list is "in the know". 
I have always read/thought/been told that gum along with carbon  
is the most archival process there is. 
I heard a comment the other day from a museum curator who said it  
was "not the most archival process". 
Now, I know that certain pigments used in the past were NOT  
lightfast. Gamboge, alizarin crimson, etc. were pigments that  
faded thru time we now know and the watercolor painters know,  
too.  Also, I know that if you leave the dichromate stain in as a  
darker brown addition underneath the gum layer, through time in  
sunlight that image will fade to gossamer green and therefore the  
print will lighten **somewhat** (found a cute little article on  
that fact about gum prints "fading on the walls of  
exhibitions").  But if using archival pigments and also taking  
into account the slight tone difference of an added dichromate  
stain now that we are not cooking our prints with heavy 100%  
sodium dichromates, etc.,, aren't gum prints really archival??   
Anyone have gum prints that have not lasted?  I've seen Kuehn's  
and Demachy's but unfortunately, photography is a relatively new  
art and thus we only have about 170 years of evidence. 
Unfortunately, I left my only conservation book (thanks, Gawain)  
at home and I am in FL for 3 wk--writing my gum book at least!
